Incidentally detected Vieussens' arterial ring‐to‐pulmonary trunk fistula in a patient with aortic stenosis

Abstract

We report a case of a 45‐year‐old man with severe aortic stenosis where computed tomography angiography incidentally revealed a fistulous communication between the conal branches of the right coronary artery and anterior interventricular artery and the left anterolateral aspect of the pulmonary trunk with a conglomerate of nondilated tortuous vessels along the anterior surface of right ventricular outflow tract.
